Compare any two graphics cards:
GeForce GTX 780 Ti vs Nvidia Titan X
IntroThe GeForce GTX 780 Ti features core speeds of 875 MHz on the GPU, and 1750 MHz on the 3072 MB of GDDR5 RAM. It features 2880 SPUs along with 240 TAUs and 48 Rasterization Operator Units.
Compare those specs to the Nvidia Titan X, which comes with GPU clock speed of 1417 MHz, and 12288 MB of GDDR5X memory running at 1251 MHz through a 384-bit bus. It also is made up of 3584 SPUs, 224 Texture Address Units, and 96 Raster Operation Units.
Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
The Nvidia Titan X should in theory perform a small bit faster than the GeForce GTX 780 Ti in general. (explain)
Texel RateThe Nvidia Titan X will be much (more or less 51%) better at texture filtering than the GeForce GTX 780 Ti. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Nvidia Titan X is the winner, by far. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
